Firstly there should be more research to see if anything is happening & if so how much.
Political agendas are not interested in science and accurate measurement only political result.
The reality is that the the science and the measurement does not support any of the GW conclusions based on flawed modelling of the UN sponsored IPCC.
Secondly there should be some serious preparations doing something.
Prepare to do something about Global Warming and end up with a 99% probability of Ice Age instead? There are 99 thousand years of Ice Age for every 1 thousand of interglacial periods induced by orbital precession into the cometary accretion disk around the sun.
Origin of the 100 kyr Glacial Cycle:
The reality is a doubling of atmospheric CO2 concentration over current levels, that the IPCC "story line" pretends, even if it were true, could not induce significant temperature change whatever its source.
Climatic temperature change OTOH generally gives rise to changes in atmospheric CO2 concentration through increase of biomass, warming of ocean hydrates & release from solution with rising temperatures.
Climatic temperature is predominantly a consequence of Solar heating/cooling arising from variation of solar radiance, plus astronomical & geophysical events affecting surface & atmospheric albedo.

Globally Averaged Atmospheric Temperatures
This chart shows the monthly temperature changes for the lower troposphere - Earth's atmosphere from the surface to 8 km, or 5 miles up. The temperature in this region is more strongly influenced by oceanic activity, particularly the "El Niño" and "La Niña" phenomena, which originate as changes in oceanic and atmospheric circulations in the tropical Pacific Ocean. The overall trend in the tropospheric data is near zero, being +0.04 C/decade through Feb 2002. Click on the chart to get the numerical data. |

Seems as though there is room for substantial doubt as to any negative effect human created CO2, Methane etc. may have on our Climate future.
At least these folks believe so:
Petition Project: http://www.oism.org/pproject/s33p357.htm
During the past 2 years, more than 17,100 basic and applied American scientists, two-thirds with advanced degrees, have signed the Global Warming Petition.
Specifically declaring:
"There is no convincing scientific evidence that human release of carbon dioxide, methane, or other greenhouse gasses is causing or will, in the foreseeable future, cause catastrophic heating of the Earth's atmosphere and disruption of the Earth's climate."
Signers of this petition so far include 2,660 physicists, geophysicists, climatologists, meteorologists, oceanographers, and environmental scientists (select this link for a listing of these individuals) who are especially well qualified to evaluate the effects of carbon dioxide on the Earth's atmosphere and climate.
Signers of this petition also include 5,017 scientists whose fields of specialization in chemistry, biochemistry, biology, and other life sciences (select this link for a listing of these individuals) make them especially well qualified to evaluate the effects of carbon dioxide upon the Earth's plant and animal life.
Nearly all of the initial 17,100 scientist signers have technical training suitable for the evaluation of the relevant research data, and many are trained in related fields.
